Vetilation trigger always opens the roller shutter

[EckeFL]

The set “Ventilation position” has no effect. The roller shutter is always opened completely.

The roller shutter is not closed after the window is closed. To test this, I moved the roller shutter below the “Ventilation position” with the window open. When I then closed the window, the roller shutter was opened again.
